Title: A process for improving dyeability of polyolefinic materials
IPC: D01F6/04
Filed: 1961-05-08
Abstract: The dyeability of a polyolefin is improved by adding in up to 20% by weight a condensation polymer having triazole rings and represented by the formula <FORM:0939248/IV(a)/1> wherein R and R1 are methylene chain, cycloalkylene, benzene nucleus, heterocyclic ring, fused benzene nucleus or a derivative obtained by connecting two of any of these groups through a sulphonyl group; X and X1 are hydrogen, alkyl, benzene, fused benzene, pyrrole, pyridine, specified derivatives of said groups, or amino or various specified derivatives thereof, and n is from 1 to 200.  The polyolefin may be polyethylene, polypropylene or polybutene.  Of the many listed condensation polymers those preferred and exemplified are polytetramethylene triazole and/or aminotriazole, polyoctamethylene triazole and/or aminotriazole; benzol, naphthyl and formyl derivatives thereof; polycyclohexylene triazole, polypyridyl aminotriazole, polynaphthalenylene aminotriazole, polyphenylene methyl and acetamino triazoles and th condensation product of 4,41-(thiodiethylene)-dibenzoic acid dihydrazide.  Solvents such as paraffin and polyethylene glycol may be used in forming the compositions.  The examples illustrate the dyeing of filamentary products of the invention.

Title: Improvements in or relating to the production of motor fuel
IPC: C10L1/02
Filed: 1932-06-13
Abstract: A mixture of ethyl alcohol, isopropyl alcohol, oils, acetaldehyde, and other compounds obtained by the catalytic hydration of gaseous mixtures containing ethylene and propylene with or without higher olefines is added to hydrocarbon motor fuel; methanol or other lower aliphatic alcohol may be blended in the fuel.  For example, 4 vol. of oil cracking gas and 1 vol. of steam are passed at 120 atmos. and 300 DEG  C. over a boron phosphate catalyst.  Or waste gases from the pyrolysis of gaseous saturated hydrocarbons are hydrated at 50 or more atmos. and 200--350 DEG  C.; the dried product is miscible with hydrocarbon motor fuel in all proportions even at -10 DEG  C.  The gases treated are preferably first freed from sulphur, and the content of olefines may be increased by washing with a solvent of the olefines, e.g. kerosene or an ammoniacal solution of a cuprous salt, and regenerating the olefines by heating or/and reducing the pressure on the solution.ALSO:A mixture consisting mainly of ethyl and propyl alcohols is obtained by the catalytic hydration of gaseous mixtures containing ethylene and propylene with or without higher olefines. The gases treated are preferably first freed from sulphur, and the content of olefines may be increased by washing with a solvent of olefines e.g. kerosene or an ammoniacal solution of a cuprous salt, and regenerating the olefines by heating or/and reducing the pressure on the solution.  In examples:--(1) 4 vol. of oil cracking gas acid 1 vol. of steam are passed at 120 DEG  atmos. and 300 DEG C over a boron phosphate catalyst; with a time of contact of 1 min. a product composed of 46 gm. of ethyl alcohol, 4 of isopropyl alcohol, 0.8 of acetaldehyde, and 33 of oil is obtained.  (2) Waste gases from the pyrolysis of gaseous saturated hydrocarbons are hydrated at 50 or more atmos. and 200-350 DEG C.

Title: Neutron detector unit and system
IPC: G01T3/00
Filed: 1973-06-08
Abstract: 1418938 Newton detector circuit GENERAL ELECTRIC CO 8 June 1973 [8 June 1972] 16782/75 Heading G1A [Also in Division G1-6] The subject-matter is identical with that of Specification 1418937, but the claims are directed to a neutron detector system and are concerned with calibration of the system. In one embodiment Fig. 3 periodic adjustment of the calibration of fission-chamber portions of in-core neutron detectors is effected using computer 33 which, via an actuator 36, operates a stepping switch 34 to connect in selected detectors. The computer provides to a gain-control device 32 a signal proportional to the current sensitivity (at time t) of the fission-chamber portions, and the device 32 sets the gain of amplifier 128 so that the output of the latter is calibrated in accordance with the sensitivity (which decreases due to the burn-up of the detectors' neutron-sensitive material). In a second embodiment Fig. 4 each detector is individually associated with its own computing and gain control system to provide continuous calibration adjustment of the fission-chamber portion by adjusting the gain of output amplifier 128.

Abstract: 770,457. Kinematographic picture films. FERNSEH GES. June 9, 1954 [June 9, 1953], No. 16932/54. Class 98(2) [Also in Group XL(b)] In the television of a kinematograph film (see Group XL(b)) control of overall amplitude or gamma is effected automatically by means of a special signal added to the film to indicate changes in the characteristics, such as contrast or density, of the pictures. In one arrangement, Fig. 1, the signal is recorded on a magnetic track 6 disposed on the opposite edge of the film to the normal sound magnetic track 5. The signal takes the form of a wave 7 varying in frequency. In another arrangement, Fig. 3 the signal is conveyed by triangular notches 31, 32 varying either in their depth or number. The notches are sensed by a contact device. Reference is also made to the use of holes, metal markers or opaque spots which may be sensed mechanically optically or pneumatically. The control signal markings may be placed on the frame lines between successive frames. The invention may be applied to control colour balance in a system for televising colour film.

Electrolyte is introduced into the cells through openings 14, 15, 16, and the cells are insulated from one another by collars 17, 18. Modifications are described in which various numbers of cells are employed. Fig. 5 shows four cells formed by dividing the outer casing 2 by a partition 22, each compartment so formed containing a cell 1, 3 mounted at the top. Electrolyte may be introduced into the cells 1, 3 through spaces round the terminals 12, 13. The cells may contain an alkaline electrolyte, the containers being made of iron, nickel, nickel-steel, &c. The Specification, as open to inspection under Sect. 91 (3) (a), states that the inner containers may be made of insulating material.
